Description

Technical Field

[0001] The present invention relates to the technical field of nursing assistance, in particular to an elderly health care and nursing auxiliary walking device. Background Art

[0002] Elderly people often face difficulties walking, unstable standing, and decreased coordination in their daily lives, which significantly reduces their safety and autonomy when engaging in independent activities. To help elderly people enhance their flexibility and coordination and improve their ability to care for themselves, a number of walking-assistance devices and exercise equipment have gradually appeared on the market.

[0003] In the existing technology, most assistive walking devices mainly focus on providing basic walking assistance functions, such as walkers and walking carts. These devices can provide a certain amount of support to help the elderly walk or take a short rest. However, these traditional devices can usually only achieve a single support or walking function, lack comprehensive physical exercise functions, and cannot effectively enhance the coordination of the hands and feet and muscle strength of the elderly. For the elderly who hope to use daily assistive devices to exercise their limbs, these devices have significant limitations. In addition, existing exercise equipment is usually designed as a fixed device and cannot be moved at will, which is not convenient for the elderly to exercise or walk at any time, limiting the diversity of its usage scenarios.

[0004] Another technical drawback is the limited adjustment capabilities of existing devices, which can't be customized to suit the physiques or exercise needs of different elderly groups. This makes it difficult for some elderly people with weaker physical fitness to use them smoothly or achieve the appropriate exercise intensity. Furthermore, common assistive devices often lack flexible hand and foot coordination mechanisms, making it difficult to simultaneously exercise both arms and legs, making it difficult for elderly people to achieve a full-body workout.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides an elderly health care and auxiliary walking device, including a base 1, wherein fixed seats 14 are installed at the four corners of the base 1, and rotating rods 3 are rotatable in the middle of the left and right sides of the rear of the base 1, and a turntable 4 is installed at both ends of each turntable 3, and a footrest 5 is installed at the outer wall end of one of the turntables 4, wherein a crank 6 is rotated at the outer wall end of the other turntable 4, and a moving rod 7 is rotated at the other end of the crank 6, and the other end of the moving rod 7 is connected to a handle 13 through an adjustment component. Limited seats 8 are installed on both sides of the outer wall of the base 1, and the outer wall of the moving rod 7 slides in the middle of the limited seat 8. Cleaning components are installed on the left and right sides of the front of the base 1, which are used to clean debris on the ground in front of the user to both sides of the device, and hydraulic cylinders 27 are installed on the four corners of the top of the base 1, and mounting plates 28 are installed on the top of the four hydraulic cylinders 27. A standing auxiliary mechanism is installed on the top of the mounting plate 28, which is used to store the seat plate 31 when the user walks, and after the elderly stand up.

[0032] Please see the attached Figure 3 The outer wall of the movable rod 9 is installed with a mounting rod 16, the outer wall of the mounting rod 16 is installed with one end of a return spring 15, and the other end of the return spring 15 is installed on the outer wall of the fixed seat 14.

[0033] Specifically, the elderly care and auxiliary walking device of the present invention is based on a stable base 1. The fixed seats 14 at the four corners provide good support, and a cleaning component is provided at the front end to clear the ground debris during the journey and ensure the safety of the walking process. A rotating rod 3 and a turntable 4 are installed on the left and right sides of the rear of the base 1. Through the linkage system of the footrest 5 and the handle, the elderly can exercise the coordination of hands and feet while walking. This design not only realizes the synchronous movement of the footrest 5 and the handle, but also can adjust the optimal position of the handle according to the height and sitting posture of the elderly through the adjustment component, providing a comfortable exercise experience. Its main use process is:

[0034] The elderly person puts his foot on the footrest 5 and adjusts the length of the movable rod 9 and the adjusting rod 11 through the adjustment component according to the sitting height of the body, so that the distance of the hand holding the handle 13 is the optimal distance. Then the elderly person can step on the footrest 5 to make the turntable 4 rotate, thereby driving the turntable 4 at the other end to rotate synchronously through the turning rod 3, so that the crank 6 is movable, and then drives the movable rod 7 to slide back and forth in the middle of the limit seat 8. At this time, the elderly person pulls the handle 13 back and forth, thereby driving the adjusting rod 11 and the movable rod 9 to swing. Under the back and forth control of the moving rod 7, the arm exercise and the foot exercise are carried out in parallel, which increases the coordination of the hands and feet.

[0035] Hydraulic cylinders 27 at the four corners of the top connect to mounting plates 28, providing height adjustment to adapt the device to different terrains and the needs of the elderly. Mounting plates 28 also feature a standing assist mechanism, allowing the elderly to stow the seat plate 31 while walking, eliminating distractions. When standing up, cylinders 33 control the seat plate 31's rise and fall, allowing the elderly to rise smoothly from a sitting position and reducing pressure on their waist and legs.

[0036] The outer wall of movable rod 9 is equipped with a return spring and mounting rod 16. When the handle is pulled, movable rod 9 drives the spring to generate elastic resistance, increasing the intensity of arm and leg exercise. The entire exercise device structure achieves synchronized movement of hands and feet. The return spring increases the difficulty of the exercise, allowing elderly people to perform coordinated hand and foot exercises, improving strength and flexibility.

[0037] To switch between walking and resting modes, the electrically operated telescopic rod 19 controls the rollers 18 to contact the ground for easier movement. In resting mode, the rollers 18 retract, and the base 1 provides stable support. The device not only provides walking assistance and allows for resting when fatigued, but also features footrests 5 and handles for exercise, helping elderly people improve their coordination while resting. A cleaning component effectively clears debris in front of the device, ensuring safe movement. The overall structural design is simple and versatile, meeting the diverse needs of elderly people for walking, resting, exercising, and getting up, improving their quality of life and self-care abilities.

[0038] Please see the attached Figure 4 The adjustment component includes a movable rod 9, one end of the movable rod 9 is rotatably connected to the other end of the movable rod 7, an adjusting rod 11 is slidably provided on the inner wall of the movable rod 9, and a plurality of mounting holes 12 are passed through the middle of the adjusting rod 11. A tightening bolt 10 is connected to the inside of one of the mounting holes 12, and the outer wall of the tightening bolt 10 passes through the through hole in the middle of the movable rod 9.

[0039] Specifically, after adjusting the high position of the handle 13, it can be removed from the mounting hole 12 by rotating the tightening bolt 10, and the adjustment rod 11 can be fixed in the movable rod 9. According to the hand height of the elderly person's sitting posture, the position of the adjustment rod 11 in the movable rod 9 can be adjusted, and then the tightening bolt 10 can be inserted into the mounting hole 12 parallel to the middle hole of the movable rod 9 and rotated and tightened to fix the position of the adjustment rod 11 in the movable rod 9.

[0040] Please see the attached Figure 8 The inner wall of the fixed seat 14 rotates with one end of a movable leg 17, and the other end of the movable leg 17 rotates with a roller 18. The inner wall of the fixed seat 14 rotates with one end of an electric telescopic rod 19, and the other end of the electric telescopic rod 19 rotates on the inner wall of the movable leg 17 through a mounting piece. One end of a return spring 20 is provided in the middle of the fixed seat 14, and the other end of the return spring 20 is provided in the middle of the movable leg 17.

[0041] Specifically, the structure within the fixed base 14 achieves a design that combines stability and convenience. The inner wall of the fixed base 14 is connected to one end of a movable leg 17, and the other end is connected to a roller 18, allowing the device to contact the ground when needed, making it easier for the elderly to push it while walking. The movement of the movable leg 17 is controlled by an electric telescopic rod 19, one end of which is mounted on the inner wall of the fixed base 14 and the other end is connected to the inner wall of the movable leg 17 via a mounting member. Driven by the electric telescopic rod 19, the movable leg 17 can rotate flexibly, thereby controlling the up and down movement of the roller 18, enabling the device to switch between walking and stationary modes.

[0042] To enhance the device's reset capability, a second reset spring 20 is positioned in the middle of the fixed base 14, one end of which is connected to the fixed base 14 and the other end to the middle of the movable leg 17. This spring 20 provides appropriate elastic resistance during movement of the movable leg 17, enabling it to quickly reset after the force is removed, ensuring that the roller 18 remains off the ground when not needed, and thus maintaining the stability of the device. This design effectively balances flexibility during walking and safety when stationary, allowing the elderly to easily switch between walking assistance and stationary stability, meeting a variety of needs such as daily walking, resting, and exercise, and enhancing the overall user experience and adaptability of the device.

[0043] Please see the attached Figure 2 , fixing frames 38 are installed on both sides of the bottom of the mounting plate 28, and a storage frame 2 is installed between the two fixing frames 38.

[0044] Specifically, the storage frame 2 can be used to store things that the elderly need to carry.

[0045] Please see the attached Figure 5 -Attached Figure 6 The standing-up assist mechanism includes two receiving slots 2 32 , both of which are provided at the top of the mounting plate 28 , and one end of a cylinder 33 is rotated on the inner walls of the two receiving slots 2 32 , and a lifting assembly is provided on the top of the mounting plate 28 , which is connected to a seat plate 31 for folding the seat plate 31 when the elderly use the device to walk. Two mounting slots 1 34 are provided at the bottom of the seat plate 31 , and the other ends of the two cylinders 33 are respectively provided on the inner walls of the two mounting slots 1 34 through mounting parts.

[0046] The lifting assembly includes two storage slots 29, both of which are opened at the top of the mounting plate 28. One end of the support rod 30 is rotated on the inner wall of the two storage slots 29. Two mounting slots 2 35 are opened at the bottom of the seat plate 31, and the other ends of the two support rods 30 are respectively rotated on the inner walls of the two mounting slots 2 35.

[0047] Specifically, the top of the device's mounting plate 28 features two second-receiving slots 32. The inner walls of these slots 32 pivotally connect to one end of a cylinder 33, which is secured to the inner walls of two first-receiving slots 34 at the bottom of the seat plate 31 via mounting hardware. When the device is in use, the elderly person can easily pull up the seat plate 31, increasing the angle between the support rod 30 and the mounting plate 28. This gradually brings one end of the seat plate 31 closer to the connection between the cylinder 33 and the second-receiving slot 32, while also increasing the central space of the device, providing a spacious area for the elderly person to stand.

[0048] In walking mode, the elderly person stands in the center of the device and controls the electric telescopic rod 19 via the button box 37, which drives the movable legs 17 to rotate, causing the rollers 18 to contact the ground and slightly lift the entire base 1 off the ground. The elderly person can then push the device using the handrails. During walking, the device's cleaning assembly, controlled by the motor 22, rotates the sector gear 24, driving the cleaning plate 25, which automatically pushes debris in front of the device to the sides, clearing the walking path for the elderly person and ensuring safety.

[0049] When an elderly person feels tired from walking, they can press a button to retract the cylinder 33, causing the seat plate 31 to drop and gradually retract into the storage slot 1 29 along with the support rod 30, creating a stable seat for the elderly to rest. In rest mode, the elderly person sits on the seat plate 31 while the electric telescopic rod 19 is controlled to lift the movable legs 17 and the rollers 18 off the ground, ensuring that the base 1 is fully in contact with the ground to maintain stability and prevent the device from slipping. This design not only ensures that the elderly can rest comfortably after walking but also ensures the stability of the device.

[0050] If the elderly need to improve their hand-foot coordination while sitting, they can place their feet on footrest 5 and adjust the handle height to suit their sitting posture. The pedaling motion of footrest 5 rotates turntable 4, which in turn, via rotating rod 3, drives the other end of turntable 4 to connect to crank 6, thereby driving movable rod 7 to slide back and forth within stopper 8, causing the handle to swing. Assisted by a return spring, the handle's rebound enhances the intensity of the exercise, allowing the elderly to effectively exercise their hands and feet in parallel and improve their coordination.

[0051] When the elderly person needs to get up from their seat, they can press a button to control the extension of the cylinder 33, raising the seat plate 31. This gradually increases the angle between the seat plate 31 and the support rod 30, providing support for the elderly person's buttocks, thereby reducing the difficulty of getting up and facilitating a smooth stand. After the elderly person stands up, the device can be switched back to walking mode, with the seat plate 31 raised to provide more space for walking. The entire design, through its sophisticated structure and user-friendly auxiliary mechanism, helps the elderly achieve seamless transitions between walking, resting, exercising, and getting up, providing all-round support.

[0052] Please see the attached Figure 7 and attached Figure 9The cleaning component includes two gears 23, and the middle shafts of the two gears 23 rotate on both sides of the base 1 respectively. The middle shafts of the two gears 23 are installed with motors 22. Gears 23 rotate on both sides of the base 1. The outer tooth tips of the gears 23 are engaged with the outer tooth tips of the fan-shaped gear 24, and a cleaning plate 25 is fixed to the middle shaft of the fan-shaped gear 24.

[0053] Protective covers 21 are installed on both sides of the base 1, the outer wall of the motor 22 is installed on the outer wall of the protective cover 21, and a roller 26 is rotated at the bottom of the cleaning plate 25, which is used to reduce the friction between the cleaning plate 25 and the ground.

[0054] Specifically, the cleaning assembly of the present invention is designed on both sides of the device's base 1. Through the transmission of gears 23 and the linkage of sector gears 24, it can achieve the function of clearing ground obstacles in front of the device while it is in motion. The cleaning assembly includes two gears 23, one located on either side of the base 1 and connected to the base 1 via a central rotating shaft. A motor 22 is mounted on the rotating shaft of each gear 23. The motor 22 drives the gear 23 to rotate, causing the outer tooth tips of the gear 23 to mesh with the outer tooth tips of the sector gear 24. When the gear 23 rotates under the drive of the motor 22, the meshing transmission of the gears 23 drives the sector gear 24 to rotate synchronously.

[0055] The middle shaft of the sector gear 24 is fixedly connected to the cleaning plate 25, so that the cleaning plate 25 swings under the movement of the sector gear 24, thereby cleaning the debris on the ground in front of the device. The roller 26 rotating at the bottom of the sector gear 24 can reduce the friction between it and the ground. The swing angle of the sector gear 24 is limited by design so that the cleaning plate 25 can effectively push the obstacles in front to the sides of the device, ensuring the safety and smooth movement of the device. Through this cleaning method, the elderly do not need to bend over or operate manually when walking to clean the ground, which effectively reduces the risk of tripping and increases the practicality and convenience of the device. The entire cleaning assembly has a compact structure and is installed on both sides of the base 1, which does not affect the overall appearance and function of the device. It is controlled by the motor 22 to achieve automatic operation, ensuring the convenience and safety of the elderly.

[0056] Please see the attached Figure 6 An armrest back 36 is installed on the top of the mounting plate 28, and a button box seat 37 is installed on the outer wall of the armrest back 36, which is used to control the operation of the electric telescopic rod 19, the motor 22 and the cylinder 33.

[0057] Specifically, the present invention includes an armrest 36 on top of the mounting plate 28 to provide support for the elderly while walking. The armrest 36 is ergonomically designed to facilitate gripping by the elderly and provide additional stability, particularly when walking or standing while using the device. A button box 37 is mounted on the outer wall of the armrest 36. This button box 37 integrates controls for multiple device functions, allowing the elderly to conveniently operate the various functions of the device.

[0058] The button box 37 controls the operation of the electric telescopic rod 19, thereby adjusting the position of the movable legs 17 and rollers 18, enabling the device to switch between walking and stationary modes. Furthermore, the button box 37 is connected to the control system of the motor 22 and the cylinder 33. The motor 22 drives the gear 23 of the cleaning component to rotate. When the elderly person needs to clean debris from the walking path, they can activate the cleaning function by simply pressing a button. The control of the cylinder 33 is used to adjust the raising and lowering of the seat plate 31. By controlling the extension and retraction of the cylinder 33 through a button, the seat plate 31 can be easily switched from a stored state to a sitting state, or to assist the elderly person in standing.

[0059] The button box 37, centrally located on the armrest back 36, allows seniors to conveniently control the device's walking, resting, cleaning, and standing assistance functions from a single location. This design enhances the device's ease of operation, making it easier and more secure for seniors, effectively improving the device's functional integration and user experience.

[0060] Working principle: When the elderly use the health care auxiliary walking device of the present invention, they can pull up the seat plate 31 to increase the angle between the support rod 30 and the mounting plate 28. At this time, the connection end position of the seat plate 31 and the support rod 30 is close to the vertical horizontal line of the connection end position of the cylinder 33 and the storage slot 2 32. At this time, the space in the center position of the device is increased. The elderly who use the device stand in the center position of the device and control the electric telescopic rod 19 by operating the button box seat 37, so that the electric telescopic rod 19 controls the movable leg 17 to rotate on the inner wall of the fixed seat 14, so that the roller 18 contacts the ground. At the same time, under the adjustment control of the four corner movable legs 17, the bottom of the base 1 is kept away from the ground. At this time, the elderly can hold the armrest back 36 to push the device to walk. During walking, if there are stones or garbage in front of the device that endanger the elderly's walking safety, the elderly can control the motor 22 by operating the button box seat 37, so that the gear 23 rotates, driving the fan gear 24 to rotate. Under the control of the fixed rotation angle of the fan gear 24, the cleaning plate 25 is driven to swing, thereby pushing the object in front of the device to both sides of the device. When the elderly are tired of walking, the cylinder 33 can be controlled by the button box seat 37 to retract the cylinder 33 and press the seat plate 31, so that the support rod 30 enters the storage groove 29. The elderly can sit on the seat plate 31 to rest. When sitting, in order to ensure that the device does not move, it is necessary to control the electric telescopic rod 19 by operating the button box seat 37 at the same time, so that the movable leg 17 drives the roller 18 away from the ground, and the bottom of the base 1 touches the ground. When the elderly are sitting quietly, if they need to move their legs, feet and arms for exercise, they can step on the footrest 5 and adjust the length of the adjustment component 9 and the adjustment rod 11 according to the sitting height of the body, so that the distance between the hands and the handle 13 is the optimal distance. Then the elderly can step on the footrest 5 to make the turntable 4 rotate, thereby driving the turntable 4 at the other end to rotate synchronously through the turn rod 3, so that the crank 6 moves, and then drives the moving rod 7 to slide back and forth in the middle of the limit seat 8. At this time, the elderly pull the handle 13 to move back and forth, thereby driving the adjusting rod 11 and the movable rod 9 to swing, and with the assistance of the reset spring 15, the tension and the reset rebound force are increased, thereby further assisting the elderly's arm activities, and under the back and forth control of the moving rod 7, the arm exercise and the foot exercise are carried out in parallel, thereby increasing the coordination of the hands and feet. When the elderly person needs to stand up, the cylinder 33 can be started directly through the control button box seat 37, so that the length of the cylinder 33 is extended. At this time, since the support rod 30 is almost immersed in the storage groove 29, the end of the seat plate 31 close to the elderly person's legs is close to the outside of the mounting plate 28. When the cylinder 33 pushes the seat plate 31, the seat plate 31 and the support rod 30 rotate, so that the angle between the seat plate 31 and the roller 18 increases, which helps the elderly person lift his buttocks and makes it easier for him to stand up.

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
